Despite all the heavy breathing, whining and wailing, the sequester is only $100 billion in cuts, many of them fake cuts. The US budget is $3.8 trillion of 2013. The sequester is a measly $100 billion, about 3.8%. A 3.8 % cut isn't going to hurt anything. And if we cannot bring ourselves to do a 3.8% cut we are doomed to go down the same drain the Greeks are going down.
You have to remember that each dollar Uncle Sam spends is a dollar taken away from citizens, who have better uses for the money that Uncle ever will. Government spending hurts the economy by reducing demand from citizens.
